> We have in place a clustering architecture as described 
> in the JBoss clustering book. 
> It currently consists of 3 nodes. 2 "read-only" nodes 
> whose CMP entity beans have read-only accessor 
> methods and a "read-write" node where the entity beans 
> have "read-write" accessor methods. 
> We use the cache invalidation architecture (based on 
> JGroups) to link the read-only and read-write beans 
> together. Changes to the RW beans cause invalidation in 
> the RO beans and the data remains consistent. 
> This all appears to work fine until we redeploy our 
> application jar files. The system continues to function 
> but we get out of date data in our RO beans. Basically 
> the RO beans are not asked to ejbLoad and hence re-
> read the data from the DB. 
> Bounce all 3 nodes and the system works fine again. 
> Redeplying to the RW node is OK but redeploying to the 
> RO node breaks the cache invalidation.
